There are now 607,426 people registered to vote in Contra Costa County and so far the county has received 110,000 vote-by-mail ballots.

Because voters are confronting a very large ballot in a presidential election year, officials expect big crowds at polling stations this year.

“We’re thinking that the lines might be really long,” county elections spokesman Paul Burgarino said. “We want to try to make it as convenient as possible to vote and not have to worry about the lines on Election Day.”
